trigger

 Your sister's death ruined your life. She had a bright, happy, future in front of her. Sirensong and her gang had burnt that future to the ground. The bitch had put a bullet in her head, and then destroyed the body. You had seen her face while she did it in the street, she wasn't a bit sorry for the atrocities she had inflicted on you and your family. Claire was gone forever.

You had gone through enough therapy to make anyone insane. That sick fuck wasn't sorry for her sins, and if the government wasn't going to make Sirensong pay you were. You had tracked the sick fucker down, at the local club, a marketplace for mercenaries and villains who offered their services to the ganglords that offered all kinds of shiny pennies.

Putting a bullet in her head wasn't good enough though, after that you stabbed, cut, and sliced into her dead body, screaming and crying. Finally you trigger as you pulled off the demonic looking full face mask, revealing the bloody face of your supposedly dead sister.
